    Question:
    I have a husqvarna 51, I recently pulled the clutch off and cleaned the oiler. After putting all back together I notice it's harder to pull start. I pull and pull and it still won't fire. Took the plug out and pulls with ease. Checked the plug and it's firing. There isn't a decompression valve on this model either.
    Any suggestions???

      Have you tried a little induce via the spark plug hole to if it will hit? If hits then you have carburetor problems or fuel supply problems; otherwise it might be out time ignition wise if you got 100+ psi compression.

      Also how far you did take down as might only needing a little grease or oil on the starter pulley pivot point or the flywheel timing could be off if the flywheel was removed. I have had several old Homelites that the users could even pull through and all it took was a little oil on the starter pulley pivot.

      Most these 51 didn't have decompression from the factory which the 55 did. Some of the aftermarket cylinders do have this as option. I know this as I rebuilt one a couple years ago and the Rotary AM PNC didn't include the plug or the CRV and I had to add this.

        What do you mean by "induce" via the spark plug hole? I've read that starter fluid may scare the piston. How do you adjust the "time ignition"? The flywheel wasn't removed, I did remove the starter cover to clean the dust out.

          I did leave out the words "fuel-mix" and yes starter fluid is not good for any two or four cycle other than diesels and they can even be damage by it if too much is used. Nothing should be used other than the regular fuel-mix which is what engine intended to run in the first.

          There is no adjustment to these ignitions. Why I mention this possible cause is if you removed the flywheel it positioning key can be damaged if the flywheel isn't reinstalled with proper torque which would allow it to slip damaging the key and therefore shifting the ignition timing.

        Thanks for the responds Eugene Rounds.

        I'll try putting fuel mix directly in the spark plug hole and see if it hits.

      Okay. I pulled the spark plug and checked if I'm getting fire, plug is firing good. Put a little fuel mix in the spark plug hole, put it all back together and pulled and pulled still won't hit.... Got fire and fuel, why can't I get just a little sign of life???
